controller-argocd-core

This repository provides a controller that enables declarative installation of
ArgoCD Core within an Upbound control plane.

Overview

The ArgoCD Core Controller facilitates continuous delivery and declarative configuration management of Kubernetes applications using GitOps principles. It deploys the following ArgoCD components in non-HA mode: argocd-server, application-controller, applicationset-controller, repo-server, and redis.

Usage

Prerequisites

Upbound account with appropriate permissions
kubectl CLI installed and configured
Upbound CLI (up) installed

Installation

Create a control plane in Upbound

UPBOUND_ORG="your_upbound_org"
# Other spaces are available, check with `up ctx`
# you need a space with enabled controller feature
UPBOUND_SPACE="space-the-final-frontier"
UPBOUND_GROUP="your_group_name"
UPBOUND_CTP="your_controlplane_name"

# Create Profile
up profile create $UPBOUND_ORG --organization $UPBOUND_ORG
up profile use $UPBOUND_ORG

# Login and switch context
up login -a $UPBOUND_ORG --profile $UPBOUND_ORG
up ctx "${UPBOUND_ORG}/${UPBOUND_SPACE}"

# Create group
up group create "${UPBOUND_GROUP}"

# Switch context to group
up ctx "${UPBOUND_ORG}/${UPBOUND_SPACE}/${UPBOUND_GROUP}"

# Create control plane
up ctp create "${UPBOUND_CTP}" --crossplane-channel="Rapid"

# Check status of control plane (should show Healthy: True)
up ctp list

# Switch context to control plane (might take a minute to become ready)
up ctx "${UPBOUND_ORG}/${UPBOUND_SPACE}/${UPBOUND_GROUP}/${UPBOUND_CTP}"

Install the controller:

This installs the controller package into your control plane, which includes the ArgoCD Core CRD and the manifests required to run ArgoCD Core.
